摘　　要：本文用钢厂废渣、浓硫酸及粉煤灰为原料制备了聚合硫酸铝铁(PAFS)。在合成中通过正交试验,从中探索了适宜的反应条件。产品经化学分析,鉴定了它的成分和性质。并以黄河水为原水,通过与市售聚铝(PAC)做絮凝对比试验取得了良好的絮凝效果。而且原水的pH值在4.5～9之间,去浊率达到99%以上。A compound flocculant, Poly aiuminous-ferric-sulphate（PAFS）, was prepared with waste slag of a steel work, concentrated sulphuric acid and fly ash. The suitable reaction conditions were investigated bythe orthogonal experiment and the content and properties of the flocculant were examined through chemical analysis. On the basis of the above work, the experiments of flocculation were done in comparison with PAC available in the markets and achieved better effect; the removal rate of turbidity reached to over 99% at pH 4.5～9.
